Python requests POST x-www-form-urlencoded

If you are working with APIs, web scraping or performing HTTP requests in Python, you may have come across the term "x-www-form-urlencoded". It is a way to encode data in the format of key-value pairs, where each pair is separated by an "&" symbol and the keys and values are separated by a "=" symbol. In Python, you can use the requests library to perform HTTP requests, including POST requests with x-www-form-urlencoded data.

Using requests.post() method in Python

The requests.post() method in Python is used to send a POST request to a specified URL. It takes two required arguments: the URL to which the request is to be sent, and the data to be sent with the request. The data can be provided as a dictionary or a list of tuples, where each tuple represents a key-value pair.


import requests

data = {"name": "John Doe", "age": 30}

response = requests.post("https://example.com/api", data=data)

print(response.content)

In the above example, we are sending a POST request to "https://example.com/api" with data containing two key-value pairs: "name" and "age". The response from the server is stored in the "response" variable, and we print its content using the "content" attribute.

Encoding data in x-www-form-urlencoded format

The requests library automatically encodes the data in x-www-form-urlencoded format when you provide it as a dictionary or list of tuples. However, you can also encode the data manually using the "urlencode" function from the "urllib.parse" module.


import requests
from urllib.parse import urlencode

data = {"name": "John Doe", "age": 30}

encoded_data = urlencode(data)

response = requests.post("https://example.com/api", data=encoded_data)

print(response.content)

In the above example, we are manually encoding the data using the "urlencode" function and storing it in the "encoded_data" variable. We then send a POST request to "https://example.com/api" with the encoded data, and print the response content.

Conclusion

Using the requests library in Python, you can easily send POST requests with x-www-form-urlencoded data. You can provide the data as a dictionary or a list of tuples, and the library will automatically encode it in the correct format. Alternatively, you can encode the data manually using the "urlencode" function from the "urllib.parse" module.
